Abstract
Abstract A method of matching a color sample mixing basic paints based on data transmitted to and from a computer via a telephone circuit. Data obtained by measuring a color sample are sent to the computer and data for coloring matching are obtained, and a test color is prepared based on the data for color matching. The observed data obtained by measuring the test color are sent to the computer to obtain correction data. The device for sending the observed data to the computer has a MODEM, an input device, an output device and a display device for presenting calculated weights of basic paints.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
216 words
A method of matching color, comprising the steps of: measuring a color sample using a color meter to obtain observed data on the color sample, sending the observed data to a computer device via telephone circuit, analyzing the observed data on the color sample using the computer device to obtain data for color matching, sending the data for color matching via telephone circuit to a metering and mixing section, metering and mixing basic paints based on the data for color matching to obtain a metered and mixed composition of basic paints, obtaining data of actual metering of the metered and mixed composition of basic paints, preparing a test color using the metered and mixed composition of basic paints, measuring the test color using a color meter to obtain observed data of the test color, sending the data of actual metering and observed data of the test color via telephone circuit to the computer device, processing using the computer device the observed data of the color sample, the observed data of the test color and the data of actual metering to obtain correction data, sending the correction data via telephone circuit to the metering and mixing section, and adding basic paints for correction to the metered and mixed composition of basic paints according to the correction data.
Claim 2
Dependent Claim
91 words
The method of claim 1 in which said metering and mixing section is formed by a communication metering apparatus comprising an integral assembly of: a MODEM which converts digital signals and analog signals in voice band to each other, an input device which is connected to the MODEM and sends observed data obtained by a color meter to the MODEM, an output device which is connected to the MODEM and outputs output signals generated by the MODEM, and a digital metering device with a display device which displays metered weight values
Claim 3
Dependent Claim
71 words
The method of claim 1 in which said metering and mixing section has: a MODEM terminal device which is connected to the color meter and receives the observed data, and an automated metering device which is coupled with the MODEM terminal device and receives the data for color matching from the computer device and meter a plurality of basic paints in amounts by weight according to the data for color matching.
Claim 4
Dependent Claim
58 words
The method of claim 1 in which said step for analyzing the observed data includes: identifying a specified color by a color code, comparing the observed dat of the color sample with the specified color to obtain differences therebetween, and correcting a predetermined data of color matching for the specified color in accordance with the differences thus obtained.
